Sounds good... don't forget you still need the recording software, monitors and headphones tho.
You can get away without the monitors for awhile. I didn't use em for years, and even now still do most of my mixing and listening through headphones.
Just make sure ya get a decent pair like AKG K-240.
Eventually you'll want to get a decent amp too.
Listening through the mixers headphone output is ok, but definately lacking in power.
You should think about what you're going to be recording too.
If you're just going to do guitar you'll be ok with the above stuff, but if you're thinking about sounding like a one man band, you'll need drums and bass at the very least. Rather than buying a VST drum machine and synth you could consider getting a few decent loop CD's to start with.
